Be it known that I, JOSEPH BscK, of theeit-y, county, and State of New York, have made certain new and useful Improvements in'Automatic Fans}. andl do hereby declare that the following is'a full,-clpar, and exact description of the same, refereuee'heing had to the accompanying drawings, making part of this specification, in whieh- I Figure 1 represents aside view of my improved fan detached from the clock-work by which it is propelled. Figure 2 is a top view of the'same, and i Figure 3 an end view of the same.

. Figure 4 represents a detached view of theworking'parts used for converting the rotary motion of the clock work to a reciprocating motion for propelling the fan. I

Figure 5 is a front view of the complete working parts, the casing, the fem-"and a portion of the spring-case being shown removed to exhihit'm'ore fully the parts shown.

Figure 6 is a plan'eor top view of the same, 'the topof the casing shown removed.

.Similar letters of reference indicate corresponding parts in the several figures.

The nature of my invention consists First, in constructing the fan with a ve'rticalwing, the top edge of which is assisted and protected by horizontal wingspand its rear end is protectedhy vertical right-angular flanges, so that by these means, when the fan is moving horizontally, the air displaced by the fan is thrown andeaused to follow in a direction where the motion of the same is desired, instead of spreading in various directions, in which case, as heretofore, the power of the fan is spent disadtantngeously. I

Second, it consists in the peculiar gear and combination of working parts employed to act with the clockwork, and to propel the fan, so that the motion impartec' from the clock-workis converted from rotary to reciprocating motion, and is regulated to worknoiseless,,anr1 with less loss of power than those now produced.

To enable others skilled in the art to make and use my invention, I will proceed to describ e its construction and operation. I

A, figs. 1, 2, and 3, represents the fan, and B the fan-stick, to which the fan is secured.

C, figs. 4, 5, and 6, represents the fan-shaft. It is arranged vertically in the casing, D, of the clock-work, which isused to propel the fan, and the said shaft G is provided with a hollow aruyE, in order to attach the fan-stick, B, to it, and the casing; D, is made with a slot, F, in whiehthe arm E passes freely.

The fan A isconstructed with a'oentral vertical wing, 11. To each side of its top edge is jointed a horizontal wing, b, which is curved upwards, as shown in figs. 1, 2, and 3, wherehy the air in contact, when the fan is in motion, is caused to be thrown downwards. And in order to throw the air in a forward direction, I providethe rear end of the fan with flanges, C C, so that the air is thiown out from the fan in the direction to meet the face of the person using it, in sitting or inlying down. I The fan-stick is provided, on its extension projecting from the fan outwards, with .trimmin'gsof silk thread, or other fabrics, to ornament the fan, and to serve for driving of! the flies and insects from the users face.

G, figs. 5 and 6, represents the clock-work, for propollin the fan, and it consists of two coiled springs,

H H, having their outer ends secured to the casing I, permanent, with the bottom of the clock-work casing, and

/ their inner' ends being attached totho spring-shaft 1; and upon this shaftis'large gear-wheel, H, or the first wheel of the clock-work, which engages a pinion, J, fixed upon the shaft 2, which has a ratchet-wheel, K, also fixed upon it, andserves the purpose to wind up the springs H H. L is a large gear-whe'el, which is placed between the pinion J and ratchet-wheel K, and is loose on the shaft 2, but connects the remainder of the clockwork gearing with the shaft 2, by means of-having the pawl and spring, M and N, taking hold in the said ratchet-wheel K, and liy means of the gear-wheel L engaging in a pinion, O, i'ix'cd upon the shaft 3, upon which shaft is again a large gear-wheel, P, which engages in a pinion, Q, fixed upon tne shaft 4, which has also a large gear-wheel, R, secured upon it, meshing in a pinion, Spiixed upon the axle 5. Upon this axle 5 is again fixed a gear-Wheel, T, which engages a pinioh, U, fixed upon the fly-wheel or balance-axle 6, upon which the fiy-wheel or balance V is secured, for the purpose of regulating the speed of the clock-work, and to prevent thereciproeating motion of the working parts attached and used between the axle 5 and the fan to produce much noise in operating.

To the lower end of this last axle, 5, oi' the clock-work, I attach a crank, W, which acts upon a spindle, 7, between the axle 5e and the fan-shaft C, by means of being connected by a red, X, with a long arm, Y, secured to the spindle 7, and thereby converting the rotary motion of the airle 5 into reciprocating motion on the arm Y of the spindle 7. And in order to increase the motion or the sweep of the fan to that obtained from the arm Y, I employ segment-gears, Z Z to transmit the motion from the spindle 7 to'the fah-shaft, of which the gear Z secured to the fan-shaft, is somewhat smaller than that secured on the spindle 7.

From the foregoing it wilLhc seen, by means of the combined working parts' by which the motion from the clock-work is transmitted to the fan, the fan is-made to make a large sweep. Its motion is well regulated, and little power is lost in crdor'to obtain such motion. Audit will be perceived, by means of constructing the fan with the wings, as herein shown, the power spent with it is more fully made use of than with those now produced.

What I claim as my invention, and-desire to secure by Letters Patent, is-

1. The employment of the fan G, constructed with the protectors 6 band a c, operated and for the purpose substantially as herein described.

2. The arrangement and combination of the clock-work G, the balance V with the crankw, the red X, the arm Y, the axle 7, the gear Z Z, and the fan-shaft (Loparated and for the purpose substantially as herein shown.

I JOSEPH BECK.
